the apex caudate, the base of lower pinne reduced; lower pinnz not shortened. 
Rachis slender, finely downy by minute hairs, soon glabrous. Pinnz above slightly 
strigose on the deeply channelled coste, elsewhere glabrous, the generally flat 
coste and costule beneath microscopically puberulous, by simple hairs, the leaf- 
tissue glabrous. Scale-like fibrils of the costae beneath few and scattered. Pinnz 
incised scarcely to the middle into broad, falcate, entire segments. Veins simple, 
12—16-jugate, the lower 3—4 forming areoles between the costule and the mem- 
brane; sometimes those of the basal pair are truly anastomosing /nervatio Goniopte- 
ridis/. Sori small, medial or somewhat inframedial. I have failed to find an 
indusium, which JENMAN describes as small and ciliate. Sporangia glabrous. 
Desvaux identified PruwiER's plate 21 with this species and was no doubt 
right; Ph. Plumieri was based on the same plate. JD. glandulosa is in its typical 
form a common fern in the Lesser Antilles. JENMAN records it also from Jamaica 
and Guiana. Nephr. dejectum Jenm. is according to a photograph of JENMAN's ori- 
ginal specimen kindly sent me by Miss Srossow together with a small fragment of 
the same not to distinguish from the type. JENMAN describes the rhizome as erect 
and the sori as indusiate. — I have seen the following specimens:

Demerara, JENMaN (N. dejectum Jenm.). 
Nephrodium Grayii, Jenman, W. Ind. and Guiana Ferns 235 1908 from St. 
Lucia, Gray nr. 17, is, judging from the description, this species. 
In Central America and South-American Andes a plant occurs, which perhaps 
is specifically different from D. glandulosa but which I now regard as a variety of 
this species. It is 
var. brachyodus (Kunze). 
Syn. Polypodium brachyodus Kze. Linnaea 9: 48. 1834. 
Phegopteris brachyodus Mett. Pheg. nr. 38. 1858. 
Dryopteris brachyodus O. Ktze.; C. Chr. Ind. 255. 
Phegopteris Seemanni J. Sm. Bot. Voy. Herald 228 tab. 49. 1854. 
Type from Peru: Pompayaco, leg. PoEpPiG (not seen). 
In pubescence, size, cutting and venation scarcely different from D. glandulosa 
type; it differs mainly by its thinner texture, darker upperside, alternate pinnz 
and its less faleate lobes. The coste and costules beneath are more decidedly 
fibrillose by red-brown fibrils, which often cover the aérophore. METTENIUS found 
the difference between this variety and the type in the goniopteroid venation of
